| 摘 要： | 列出核燃料运输车2次缓冲装置的纵向动力学微分方程,采用变步长的Runge -Kuta积分法,对其进行了7种工况下的纵向动力学仿真分析。结果表明,在核燃料运输车上采用3级刚度的2次缓冲装置,满足核燃料货包在各种工况下的纵向加速度≤1 5g的要求,而且采用较大的摩擦因数有利于减小核燃料货包的纵向滑动行程

| Abstract: | The longitudinal dynamics differential equation of secondary cushioning unit of nuclear fuel truck was presented.Adopting Runge-Kuta integral,longitudinal dynamics simulation analysis under 7 loads series was carried out.Results show that when third class stiffness secondary cushioning unit was equipped on nuclear fuel truck,longitudinal acceleration of nuclear fuel package under all sorts of loads series less than 1.5g,and the biggish friction coefficient is propitious to reduce longitudinal glide distance of nuclear fuel package. |
